I am using R version 3.0.1 (2013-05-16) on Platform: x86_64-w64-mingw32/x64
(64-bit) and lme4_0.99999911-3.
I run the following code from Douglas Bates "lme4: Mixed-effects modeling with
R" (June 25, 2010) pg 14 and do not get any iteration information.
I get the same results if I use verbose=TRUE or verbose=1L.
> lmer(Yield~1|Batch,Dyestuff,REML=FALSE,verbose=1)
Linear mixed model fit by maximum likelihood ['lmerMod']
Formula: Yield ~ 1 | Batch
Data: Dyestuff
AIC BIC logLik deviance
333.3271 337.5307 -163.6635 327.3271
Random effects:
Groups Name Variance Std.Dev.
Batch (Intercept) 1388 37.26
Residual 2451 49.51
Number of obs: 30, groups: Batch, 6
Fixed effects:
Estimate Std. Error t value
(Intercept) 1527.50 17.69 86.33
I noticed this in the structure of the output:
..@ optinfo:List of 4
.. ..$ optimizer: chr "Nelder_Mead"
.. ..$ control :List of 1
.. .. ..$ verbose: int 0
.. ..$ conv : num 0
.. ..$ warnings : list()
Please advise me on how to obtain iteration information with lmer.
Thanks,
Roy Robertson
